UNITED STATE MA'r'raEss srmNG BINDING momma Edward Turgeon,

by mesne a Corporation, Chicago,

l Illinois Minneapolis, Minn., asignar,-

ents, to Nachman S ed Y prinsll Ill., a corporation of 57 Claims.

My invention relates to machines for fabricating mattress spring assemblies, and generally stated, consists of the novel devices, combinations of devices andarrangement of parts hereinafter described and defined in the claims.

Hitherto, mattress spring assemblies have been made by disposing upholstery springs in parallel rows and tying` the rows together by means of helical tie wires encircling and interlocking together the lapping or contacting terminal portions of the adjacent springs of two rows thereof at each operation.

The preferred embodiment of the present invention is directed particularly to mechanism .for automatically performing the major and most diiiicult operation incident to coupling rows of springs. For example, the helical tie wires are rotated and advanced along guiding device, so.that they will encircle the adjacent or contacting portions of the properly relatively disposed rows of upholstery springs. Also various other operations are automatically performed, such as the automatically stopping of Lthe spiral feeding of the helical tie wires when desired portions of two Also the alignment and proper `positioning of the rows of upholstery springs preparatory to effecting the coupling thereof by the helical tie wires is performed in this machine by very simple manually operable means.

A commercial form of the improved machine is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views.

the nature of the called to Fig. 17 which shows finished product, to wit: the mattress spring assembly, which, in the prgsent instance, is made up of conventional upholstery springs A .wires b. The helical tie-wires b are of small dameter but of long pitch, andare rotated and advanced laxially into encircling relation to overlapped portions of the terminal coils of two rows of said springs A, springs.

'Attention is first The framework proper of the machine is shown with the drawings as supported upon a pair of floor-engaging angles or members 20. This framework proper is really made up of two laterally spaced apart upright frames. themselves constructed and equipped with mechanism hereinafter described in right and left arrangement.

One of these frame members is rigidly secured to the lbase members 20, and the other is pivoted thereto. The rigidly secured frame member is shown at the right in Fig. 1 and at the left in line IS-IS of bound together by helical tiethereby coupling said rows of are pivotally con.

Located in the lower portion of the-machine and extended from side to side thereof is a footactuated U-shaped treadle lever 25, the arms of which are pivotally connected with the iixed frame member at 26 to a bracket 21 that projects from the fixed oblique brace 23. This lever is normally held at the upper. limit of the movement in the position shown in Figs.l 3, 4 and 5 by coiled springs 28 attached to the arms thereof and to the xed posts 2|.

At each side of the machine there are mounted link-like draw-bars 29, which, Y at their lower ends, are pivotally connected to the projecting ends of studs (see particularly Figs; 3 and 5) that are rigidly secured to and project outward, 1y from the arms of the foot treadle 25. At their upper ends, the Adraw-bars 29 are rigidly secured to strap-like cross arms 3| provided at their ends with lateral projections 32 and 33 that are preferably roller-equipped studs. The rollers of studs 32 roll against the outer edgesof the xed posts 2| and are held for vertical travel by keeper straps 34 secured to said posts 2|. 'I'he rollers of the studs 33 roll against downwardly flaring cam surfaces 35 formed as part of keeper brackets 36, the outer arms of which hold the said rollers for action on said cam surfaces 35. is only necessary to state that when treadle 25 lis stepped on and forced downward, draw-bar 29 will be pulled downward, causing the roller or stud-equipped cross arms 3| to force the pivoted side frame. 2|22' laterally toward the relatively xed frame 2|22. l

Also at one side of the machine, see Figs. 3, 4 and 5, just outward of the bars 29 is a straplike link 31, which, at its upper end is pivotally connected to a hand-operated lever 38 (betweenthe ends of the latter) that is pivoted to the fixed part of the main frame at 39. Also pivoted at one end at 39 is a second alignment plungeractuating lever 40. Here it should also be noted that link 31, at its extreme upper end, has a laterally projecting lug 4| that underlies the intermediate portion of lever 40. Loosely hung over the intermediate portion of lever 4|) is a coupling link 42, the lower end of which is in the form of a slotted loop that embraces a stud or projection 43 onvthe link 31. At its lower end, link 31 is pivoted -on the projecting'end o f the stud 30, on which stud also the adjacent draw bar 29 is pivoted. At their lower ends the draw bar 29 and adjacent link 31 respectively, (see particularly Figs. 3, 4 and 5), are connected to the extended ends of coiled springs 44, the other ends of which springs are pivotally attached to a stud 45 on the' extended end of the adjacent xed bracket or frame extension 21. The spring or springs 44 act on a line slightly above the axis of pivot 26 and, hence, co-operate with the spring 28 to yieldingly hold the foot pedal 25 raised and to move the 'same to a raised position when released from the foot action. 'I'he function of link 42 will appear in the description of the operation.

At this point, it

As a means for holding a supply -of the helical tie-wires b, a magazine or box-like holder 46, see Fig. 3, is preferably provided.

The wires will mally held be fed from thebox 46 two at a time and willbe manually directed through lead holes 41, see particularly Figs. 3 and 11, formed in the frame posts 2| and 2|' at the receiving side of the machine.

Rigidly secured to the cross beams 22 on the one side and to the cross beams 22 on the opposite side are upright die blocks 48, (see particularly Figs. 6, 11, 13, 14 and 15). These die blocks 48 are formed with semi-cylindrical guide channels 49; the one series with the axes aligned with one of the lead holes 41, and the axes of the other of which series are aligned with the -axes of the other lead hole 41 so that the tiewires fed through the respective leadpassages will be independently conveyed through the opposed channels of the two series of die blocks.

'I'he guide channels in the two opposed die blocks that are at the extreme delivery side of the machine, to wit, at the extreme right in respect to Fig. 11, for example, do not run completely through the said die blocks, but are closed or partly closed by stop lugs or shoulders 50, best shown in Figs. 11 and 15. The important purpose of this stop arrangement will be made clear in the The numeral 5| (Fig. 6) indicates tie straps rigidly secured to the beams 22 at the one side and to the beams 22 at the other side and spaced from the respective die 'blocks 48. y

Extended through the iixed posts 2| and through the die blocks 48 ls a pair of long shafts 52; and in a similar manner extended through and journalled in the movable posts 2| and corresponding die blocks 48 is asimilar pair of long shafts designated by the same'numeral 52. At the one side of the machine the shafts 52 extend into or through journal boxes 53 secured one to the right hand fixed posts 2| and the other to the right hand movable posts 2|. The companion shafts 52 are provided with gears 54 that mesh with pinions 55 on short drive shafts 56 that are journalled in and are extended outward 4through the heads of the journal boxes 53 and are providedwith driving pulleys 51.

The shafts 52, adjacent to the die blocks 48, are provided with circumferentially grooved spinning rollers or roller-acting portions 58 which,

aswill hereinafter more fully appear, have aparticular 'function' in that they frictionally cause the respective helical tie-wires to rotate and at the same time will advance the latter axially through the channels 49. grooves 58' of the spinner-acting hubs 58 are spaced to correspond to the pitch of the helical tie-wires.

Means will now be described for pressing the said coil tie wires arms 59 are pressed toward the same.

'I'he transversely aligned but spaced arms 59 are norspaced as shownin Fig. 6 by U-shaped description of the operation.

The spacing of the tie wires b when the when their ends drop on nected to a tie plate pacing springs 63. l(Also, the arms 58 are provided with stop lugs 84 that are engageable with the faces of the adjacent die blocks 48 to limit the movements of the arms towardgthe said die blocks 48 and the helical wires .b when the movable side of the frame is pressed toward the fixed side by means already noted but to be more fully explained in the'description of the operation.

In preparing the machine for each operation a series of the mattress springs A are dropped in the spaces between the spacing springs 68,`which springs 6,3V perform an additional function of spacing and locatingthe mattress springs A for application of the helical tie-wires. 'I'hese springs A are manually dropped into-the positions indicated and they will be properly stopped to fixed locating pins or projections 65, best shown in Figs. 8 and 9. In Fig. 8 one of the upper springs manually located as just noted is the upper spring,`and the lowerspr'ing is shown in a position which it will occupy after the helical binding wire `has been applied thereto and the spring assembly dropped one step.

Mounted for sliding movement on the faces of the die blocks 48 are plunger-like slides66which, near their upper ends, are by coupling `rods 66 pivotally connected to arms 61 carried by rock shafts 68, (see particularly Figs. 4, 6 and '1), mounted on suitable bearings on the opposed frame members and provided with arms 68 connected by links 18 to the heretofore noted hand lever 48. The slidesl 66, as will hereinafter more fully appear, operate as retaining guides for directing the. helical tie wires around the adjacent aligned portions of the springs purpose are made concave at' ends and provided with coil clearing notches 1|, (see particularly Figs. 8, 9, 10 and 13).

At their intermediate portions the slides 68 are shown as provided with projecting pins 12 that project through guide slots 12 in the respective die blocks 48 and by coiled springs 13 are con- 14 which is bolted or` otherbeams 22 and 22', (see par- 13, secured at wise secured to the ticularly Fig-.6) Tension springs one end to the machine frame (Fig. 6) and engaged at their other ends with pins 12 connected with the members 66, hold the latter yleldingly engaged with the-respective die-blocks 48. As an additional and preferable feature, rocking fulcrum pins or blades 15 are interposed .between the slides 66 and concave seats in the dies. Under upward and downward movements of the slides 68 the fulcrum pins one side to the other of a dead center and tend to hold the said slides in the one or the other extreme position in which they are set by means already noted and which will be made clear in the description of the operation.

Working through each die block 48 and through the semi-cylindrical guide channels thereof are ejecting pins 18. The ejecting pins that are on the same side of the machine, or in other words, on the same frame section, are connected to a common bar 11 that is subject to the action of rocker arms 18 on a rock shaft 18, (see particularly Figs. 5 and 6). Coil springs 88, best shown in Fig. 6, are anchored to the bars 14 or other fixed part of the frame work and to arms 8| projecting from the rock shaft 18.` These springs 88 exert force normally holding the ejecting pins 16 retracted, as shown in Fig. 6.

The rock shafts 19 at one end are provided with arms 82, see particularly Figs. 3, 4 and 5,

respectiveA 15 move from 'amadosconnected by cross tie A, and for this provided that are connected by links 83 to a hand lever 84. This lever 84 is intermediately pivoted to the lower end of a hanger strap 85, (see particularly Figzet) which, at its upper end is pivoted to a bracket 86 on the upper end of one of the v movable frame posts. A

' Directing attention again particularly to Fig. 6, the vnumeral 81 indicates ejecting plungers or slides mounted for vertical movements in depending channel-like guides 88 to the die blocks 48. These ejecting slides orplungers 81 at their 'upper ends are provided with laterally projecting beveled hook lugs 88; andat their lower ends, the lower ends of the ejecting plungers 81 that areon the same side of the machine or frame section, are connected to'common bars 88, (see particularly Fig. 6), the ends of which work in guide grooves 8| formed in the inner faces of the frameposts 2| and 2|' The two connecting bars 98 at their ends are rods 82. Right-handand left connecting rods 82 at their central portions are pivotally connectedlto the lower ends'of links 83, the upper ends of which latter are pivotally connected at 84 to the intermediate portions of the arms of a manually operated lever-acting bail 95 shown aspivoted at 86 to brackets 81 supported from the fixedv frame posts 2|, best shownin Fig. 1.

Power for operating the machine described may be and preferably is an electric motor 88 shown as secured to a supporting platform 88 pivoted at one end to floor brackets |88. The-rotor of this motor 88 carries a driving pulley |8|. A normally slack driving belt |82 runs over or inl frictional contact with the-driving pulley |8| and. over the two pulleys 51 previously described as being located on the spinner driving shaft 56.

Aspring |83 anchored to one of the posts2l and to the free portion of the motor supporting y vplatform 88, normally holds the motor raised so/'V that its pulley |8| vwill not put tension on the driving belt |82 and, hence, will not drive the mechanism of the machine. Means is further whereby when the foot treadle 25 is stepped on and depressed, the draw bar 28 is drawn downward with its cross bar 3|, and themotor will`be depressed and driving tension .will be put 'on the belt |82. A connection for this purpose is a link or rod |84 connected at its upper end to the cross bar 3|, and at its lower end .to the extended portion of the motor-supporting platform 88.

The numeral indicates a receiving deck secured at the bottomof the machine and on to which the finished product, to wit; the mattress spring assembly, will be delivered from the machine.

In Fig. 17, which shows the finished product or apart thereof, the character b shows the ends of the helical tie wires twisted orbent to anchor and tie the ends of the tie-wires. This binding at b', as will appear in the description of the operation, will usually be performed manually by the use of pliers andthe like.

chine, the mattress' springsA will be manually placed in the pockets or spaces between the laterally spaced pairs of arms 58 and their connecting springs 69, with the lowerparts of the end convolutions of said springs resting on the aligning pins 65.

The movement of the hinged side of the frame toward the fixed side also slightly compresses the springs A and will insure proper holding of the springs for the application of the coiled tiewires. Fig. 8 shows the manner in which the aligning pins 65 stop the coils in position for the application of the coiled tie-wires around overlapping adjacent portions of upper and lower springs A.

A summary of the operation of the machine is as follows:

Figs. l, 3, 6 and '7 show the parts of the machine in normal and idle positions. To start the machine into action, the operator steps on the treadle 25, depressing the same and causing' the rod 404, draw-bar 29 and link 31 to be drawn downward; thereby performing the following operations a, b, and c.

(a) Depression of the rod IM lowers the motor,

forces its driving pulley IUI against the beltl02 pulleys 51 of shafts.

and tightens the latter onto 56, thereby rotating the latter and the spinning rollers 'or hubs 58.

(b) Depression of the draw-bar 29, in a manner earlier described, causes the roller-equipped studs 53 to force the hinged or movableside of the frame .Qward the relatively fixed side of the frame; and movement of the pivoted side of the frame toward the fixed side of the frame section carries the hinged` arms 59'on the movable frame toward the arms 59 on the fixed side of the frame and, actingthrough the springs 53, causes the presser rollers 6| to move. toward the cro-operating" spinning rollers 58 in position to press -the helical tie wires against said spinning rollers, as will presently more clearly appear.

(c) Pulling down or depressing of link 31 at the extreme movement of thelatter, pulls down coupling link l2 and depresses lever 40; and depression of lever 40, operating through the links 10 and arms 59, rocks vthe shafts 68, causing the aligning slides 65 to be moved downward so that their bevelled or concave lower ends will be positioned to guide the spiral tie-wires through the channels 49 and properly around the lapping adjacent portions of upper and lower coils.

The operations a, b and c above enumerated,

all follow from depression of foot treadle 25 and when the machine is thus set into action, the helical tie wires b will be introduced or inserted through the lead holes 41 and will come into contact with the rst of the presser rollers 6|. By the presser rolls 8l, the coiled tie-'wires b will be kept in frictonal contact with the spinning rollers 58, and their convolutions will run in the annular grooves 58 of said spinning rollers. Obviously, when the tie wire is caused to rotate in the endless annular grooves 58', travelling movement to the tie wires will beproduced. The rotation of the helical tie-wire causes the same to travel axially and the axial travel will correspond to the pitch of the saidtie wire. The frictional contact between the tie wire and the spinning rollers is suiiicient to cause this end- Wise travel under ordinary resistance, but they can slip under certain conditions presently to be noted.

As the tie binding wires are rotated, they will be guided in the grooves or channels 49 and will be caused to pass around the lapping or adjacent lportions of the springs A, tying the same securely together. When the tie wires have Figs. 1, 3, 6 and '1. Under this upward lever 40,

tions described, causing all of the aligning slides been threaded into encircling relation to the overlapped portions of the last pair of springs, the last ends of the tie wires will engage the stop shoulders 50 at the extreme ends of the channels 49, and further feeding movement of the spiral tie wires will be stopped. Here it will be further explained that when the tie wires are thus stopped and resistance is exerted to endwise travel, there will be slippage of the tie wire along the spinning rollers 58 and presser rollers 6|. 'It may be here further stated that the spacing of the grooves 58' in the spinning rollers corresponds to the pitch of the tie wire.

lWhen the above operations have been completed, the operator removes his foot from the foot treadle 25, and the latter will be springpressed upward, thereby restoring the motor to its raised position, stopping the latter and cansing the movable frame section to move away from the fixed frame section so that the parts will be again restored to the position shown in last noted opera'- 31 causes its latend 4| to engage and press thereby, through the connection, upward movement of link erally bent upper to be moved upward and tions shown in Fig. 6.

As the next operation, the operator pushes upwardly or forwardly on lever 8l and through the connecting links 82-83, (see Fig. 5), rock shaft 19 and `arm 18 moves the opposing ejecting plungers 16 inward, thereby positively .forcing the coiled tire-wires and connected portions of the springs A oi from the aligning pins: 65, so that back to normal posithe connected springs may be pulled or forced downward, bringing other springs later into position for the operations already described.

'.Ihe next operation performs the downward feeding movement ofthe assembled springs as follows:

The operator moves the lever-acting bail 95 upward, as shown in Fig. 5. This causes the ejectlng slides 81 to be moved upward to the dotted line positions shown in Fig. 6, with the hook lugs 89 engaged with the previously applied tie-wire coils b and connected coils A. Next, the bail is moved downward or back to normal position, which carries the ejecting slides 81 and their lugs 89 downward to normal or fullline position shown in Fig. 6 and imparts to the spring assembly structure, onestep of downward movement equal to the -diameter of one of the springs A; and this downward movement of the spring structure causes the upper portions of the coils A to drop onto the projected ejector plungers 15, as indicated by full lines in Fig. 9. As

-to Fig. 5, back to normal position, thereby retracting all of the-ejecting plungers 16 and permitting the upper part of the end coils of the springs A to drop onto the aligning pins 55, as shown by dotted lines in Fig. 9.

The machine described will accommodate or handle springs A that vary considerably in diameter. l'Ihe machine designed and put into actual use I have found eillcient for all of the purposes had in view, and the machine will handle springs varying from three and a half to four and a half inches in diameter. The deck |05, in the machine as designed, catches the fabricated spring structure and turns the same horizontally onto the floor or the like so that by the tie-wires may be bound or upset as indicated by b' in Fig. 1'?.

The springs designated at A have generally been designated as supporting springs but they might as well be called body springs since they make up the main elements of the spring assembly. It should be noted that the machine described simultaneously feeds two spiral tiewires, and applies the upper to connect the upper ends of the aligned body springs and applies the lower to connect thelower ends of said springs. In first starting the machine, to make the spring assembly, the first upper and lower spiral tiewires are applied only at one side of the spaced springs A; and in the final operation of the machine, the two last tie-wires are applied only to one edge of the last row of springs.

For lack of a better term, the finished product is herein designated as a spring assembly, but such structure in the trade is usually simply designated as a mattress spring.

In the drawings of this application and in the above specification, I have, in accordance with the patent statutes, described what I at present believe to be a preferred embodiment of myinvention, but I do not thereby intend to limit myself or the scope of the invention, as many changes and modifications may be made without departing from the spirit of the invention, and all such I aim to include within the scope of the appended claims.

Obviously, the short grooved rollers 58 cooperate with the presser` rollers 6l to guide the helical tie wires b into and through the guide channels 4,9 of the die blocks I8, said guide channelsbeing thus of secondary .importance as guiding elements, except insofar as they may serve to prevent displacement or bending of the tie wires due to the front ends of portion at any point with a glancing blow, as may occur if the locating pins are not accurately positioned for engaging the overlapping spring portions at exactly the right points to maintain them out of the path of the forward en d of the tie wire during the rotary and advancing movement of the latter.

It will be noted springs fed into the machine following each operation of the tie wire feed rolls, rests by gravity upon the several pairs of locating pins and that the latter function not only as supports for` but also as means for automatically causing said springs to become self-positioned upon said pins with respect to the spaced-apart points of sup-l port and the consequent arcuate portions of the kterminal coils of the springs that project below the level of said pins, no means other than said pins being provided for effecting such initial gravity positions of each new row of said springs which, later, are held firmly in place by partial compression as above described. This constitutes a material advantage of the machine since it the latter striking a springv Y coils in closely assembled relation,
